[Yann E. MORIN]

commit: https://git.buildroot.net/buildroot/commit/?id=b7a5b9d06d484700fc4fcbd354f2c15e0422688c
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

openssl is an optional dependency which is enabled by default since at
least 2007 and
https://github.com/krb5/krb5/commit/4c17f25c0f106ec8e3aad2cee4e7a24f66b5a65d

Enable DES, MD4 and RC4 in openssl to fix build failure raised since
commit a83d41867c8d69a77d5cd0a665aa216af5340359
